    heater fan underdash electrical connections

    Hello,

    I wrote them down, but can't find the page...

    I rebuilt my heater box. I reinstalled it. I need to reconnect
    the 4 wires to the front side of the heater from the slider
    switches.

    On the heater box, there is "+, 2/3, 1/3, -". I have black,
    yellow, purple and two tone.

    Can someone please tell me which connects to which? I thought
    it was:

    yellow = "2/3"

    black = "+" two tone = "-"

    purple = "1/3"


    I can look for the page, but I'd *really* like to get
    everything put together ASAP.

    Thanks!
    Bigby

    Never mind! I found my sheet!

    FYI:

    Yellow/Green = "+"
    Purple = "2/3"
    Yellow = "-"
    black = "1/3"

    or, in diagram form:

    trunk

    purple(2/3)


    Yel/Gr (+) Yellow (-)


    black (1/3)


    glovebox steering wheel

    As one looks at a piece of paper held up, and
    aligned with the glovebox and steering wheel.

    This is for a 1976 BWM 2002 with Behr A/C. YMMV.
